Antifouling detergent for hard surfaces

Abstract

An antifouling detergent for hard surfaces, which can be used in home to confer an excellent antifouling performance and an ability to prevent re-deposition on hard surfaces in a toilet, a bathroom and a kitchen; and a method of antifouling and washing hard surfaces of toilet bowls, which includes treating the surfaces with an antifouling detergent composition.

1. A method of antifouling and washing hard surfaces of toilet bowls, comprising:
 treating the surfaces with an antifouling detergent composition comprising a polymer having a weight-average molecular weight of 5,000 to 60,000 and consisting essentially of monomer unit A and monomer unit B, wherein the molar ratio of monomer unit A/[monomer unit A+ monomer unit B] is ⅔ to 0.9 wherein the monomer unit A is di (ω-alkenyl (C 2 -C 10 )-dialkyl (C 1 -C 3 ) ammonium salt in an amount of 10 to 90 mol-% relative to the whole monomer units, 
 the monomer B is at least one monomer derived from a monomer selected from acrylic acid or salts thereof, methacrylic acid or salts thereof, and maleic acid or salts thereof. 
 
     
     
       2. The method according to  claim 1 , wherein the antifouling detergent composition further comprises a surfactant. 
     
     
       3. The method according to  claim 2 , wherein an amount of the surfactant is 0.00 1 to 50 mass-%. 
     
     
       4. The method according to  claim 1 , wherein the antifouling detergent composition further comprises a water-soluble solvent. 
     
     
       5. The method according to  claim 4 , wherein an amount of the water-soluble solvent is 0.1 to 50 mass-%.
